Thread: How to do duel Zero. Sub/Super

Get a scope with a BDC reticle and see which marks match up with the subsonic drop at different ranges.
I think dialling with two different loads will end up badly at some point.
I tried sub loads in my 7/08. With my scope on 7x the thin/thick crosshairs transion on the vertical cross hair was spot on at 100yds for the sub loads. At 20yds I was 2" low and at 50yds about 4-5" low from memory.
